Diesel EFI Systems.
(OP)
My company manufactures aftermarket performance diesel parts. Mainly for tractors. I would like to develope a EFI Common Rail system for our engines. I'm looking for some suggestions on companies I could work with, and ideas were to find parts that are already avialable. The engines we build generate around 2000-3000 hp, and can consume from 1200cc to 2000cc of fuel per revolution. Right now our fuel system consits of a Sigma style aftermarket pump. Any suggestions would be helpfull. Mainly looking for ideas on ECU and Injectors.

Bosch and Siemens are two big names in automotive-scale systems but I don't know if they extend the common-rail concept to such big engines.

At 1200rpm, 30% efficiency, 10cc/rev would get you about 3000hp.

You need to talk to Exergy Engineering: http://www.exergyengineering.com/

Hope this helps, Turbo
Here is an article they put out: htt

With large diesel engines, such as the Wartsila, Man B&W, MAK etc. they usually size the pumps to deliver about twice the maximum fuel consumption.
This is partly to do with the fact that the fuel is heated and the returning (heated) fuel is mixed in the high pressure circuit with cooler make up fuel and the objective is to try and achieve stable heater control.
I couldn't say how the pumps are sized for gasoil or diesel.

Delphi and Bosch both manufacture common rail pumps. Denso has a first generation pump now on the market.
Filtration: UFI, or Racor make filters for common rail systems.
For fuel feed from the tank, Bosch, Continental, or TI Automotive are your choices.
I am a recently retired Sr. engineer from Chrysler and have been working on common rail systems for years.

Not exactly an answer to your question, but a company with interesting fuel injection technology (similar to the CAT HEUI technology) is Sturman. You may want to take a look...

Remember when we were using that prototype 20ksi common rail system from DTC (now known as Exergy) on the TRC engine back in about 1993? Man, was that system crude! I remember the control box DTC provided for it consisted of three knobs: one for rail pressure, one for BOI, and one for PW.
Worst of all, after every rebuild we'd spend hours chasing leaks in the high-pressure plumbing. The drill usually went like this:
step 1- motor engine up to speed using dyno.
step 2- turn knob to slowly increase rail pressure.
step 3- hit emergency stop on dyno controls when test cell is instantly filled with super-atomized fuel cloud (thus becoming a potential fuel-air bomb) due to 20,000psi fuel rail leak.
step 4- climb out from under desk, take fingers out of ears, change underwear, fix leak, and repeat steps 1-3.
And getting that TRC engine to light-off with its 12:1 compression ratio was always pretty exciting. We would motor the engine up to speed, set the BOI and PW, and then slowly bring up the rail pressure. When that 92 cubic inch single cylinder TRC engine, with its 8 atm of boost, would finally light-off, it would create an un-godly roar, shake the control room, and cause everyone in there to jump a foot into the air. We had to wear ear plugs even in the control room, and the noise and vibration were so bad that you felt physically fatigued after only about 1 hour of running.
Other than that, it was great fun! Check out Marius' "objective" technical write-up on the program. I was the guy running the engine and strangely I don't recall most of this:

42000 KJ/Kg x 0.8 Kg/Ltr x 2 Ltr x 40% efficiency = 26880 KJ
per rotation.
This means that at a power of 3000 hp the engine runs:
3000 hp x 0.7355 KW/hp / 26880 KJ/rot x 60 rot/min = 4.9 RPM
I have never seen such an engine running that RPM at max. power.

You can buy Bosch MS-Series Diesel ECUs and injectors directly from www.bosch-motorsport.com . They don't come cheap, but are suited for the purpose (Diesel), and for development and one-off purposes the prices are par for course.

In trades that deal with small liquid volumes, it is common to make volume measurements not in cubic centimeters, but in cubic millimeters.
Conveniently, just as 1 cm^3 is roughly a milli-litre,
it works out that 1 mm^3 is roughly a micro-litre.
All, please check units when quoting numbers.
